1、简介

2、AWT

2.1、AWT简介

2.2、组件和容器

·Frame

package lesson1;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestFrame {
	public static void main(String args[])
	{
		//Frame,JDK,看源码
		Frame frame = new Frame("我的第一个Java窗口！");
		
        //需要设置可见性
		frame.setVisible(true);
		
		//设置窗口大小
		frame.setSize(400, 400);
		
		//设置背景颜色
		frame.setBackground(new Color(85,150,68));
		
		//设置大小固定
		frame.setResizable(false);
		
		frame.addWindowListener(new WindowAdapter() {
			//窗口关闭的时候需要做的事情
			public void windowClosing(WindowEvent e) {
				//结束程序
				System.exit(0);
			}
		});
	}
}

关闭事件，窗口关不了

package lesson1;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestFrame2 {
	public static void main(String args[]) {
		MyFrame myframe1 = new MyFrame(100,100,200,200,Color.blue);
		MyFrame myframe2 = new MyFrame(300,100,200,200,Color.red);
		MyFrame myframe3 = new MyFrame(100,300,200,200,Color.yellow);
		MyFrame myframe4 = new MyFrame(300,300,200,200,Color.green);
	}
}

class MyFrame extends Frame{
	static int id  = 0;  //可能存在多个窗口，我们需要一个计数器
	public MyFrame(int x,int y,int w,int h,Color color) {
		super("MyFrame"+(++id));
		setBackground(color);
		setBounds(x,y,w,h);
		setVisible(true);
		
	}
}

·Panel

解决了关闭事件

package lesson1;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

//panel可以看成是一个空间，但是不能单独存在
public class TestPanel {
	public static void main(String args[]) {
		Frame frame = new Frame();
		Panel panel = new Panel();
		
		//设置布局
		frame.setLayout(null);
		
		//坐标
		frame.setBounds(300,300,500,500);
		frame.setBackground(new Color(40,160,32));
		
		//panel设置坐标，相对于frame
		panel.setBounds(50,50,400,400);
		panel.setBackground(new Color(193,15,60));
		
		frame.add(panel);
		frame.setVisible(true);
		//监听事件，监听窗口关闭事件
		//适配器模式
		frame.addWindowListener(new WindowAdapter() {
			//窗口关闭的时候需要做的事情
			public void windowClosing(WindowEvent e) {
				//结束程序
				System.exit(0);
			}
		});
	}
}

2.3、布局管理器

·流式布局

package lesson1;
import java.awt.*;

public class TestFlowLayout {
	public static void main(String[] args) {
		Frame frame = new Frame();
		
		//组件——按钮
		Button button1 = new Button("button1");
		Button button2 = new Button("button2");
		Button button3 = new Button("button3");
		
		//设置为流式布局
		//frame.setLayout(new FlowLayout());
		frame.setLayout(new FlowLayout(FlowLayout.LEFT));
		frame.setSize(200, 200);
		
		//把按钮添加上去
		frame.add(button1);
		frame.add(button2);
		frame.add(button3);
		
		frame.setVisible(true);
	}
}

·东西南北中

package lesson1;

		for(int i= 1;i<=4;i++) {
			p4.add(new Button("for-"+i));
		}
		p3.add(p4,BorderLayout.CENTER);
		
		frame.add(p1);
		frame.add(p3);
		
		frame.addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent e) {
				System.exit(0);
			}
		});
	}
}

2.4、事件监听

package lesson2;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestActionEvent {
	public static void main(String args[]) {
		//按下按钮，触发一些事件
		Frame frame = new Frame();
		Button button = new Button();
		//因为，addActionListener()需要一个ActionListener，所以我们构造一个ActionListener
		MyActionListener myActionListener = new MyActionListener();
		button.addActionListener(myActionListener);
		
		frame.add(button,BorderLayout.CENTER);
		frame.pack();
		
		WindowClose(frame);
		frame.setVisible(true);
		
	}
	
	//关闭窗体事件
	private static void WindowClose(Frame frame) {
		frame.addWindowListener(new WindowAdapter() {
			
			public void windowClosing(WindowEvent e) {
				System.exit(0);
			}
		});
	}
	
}

class MyActionListener implements ActionListener{
	public void actionPerformed(ActionEvent e) {
		 System.out.println("aaa");
	 }
}

package lesson2;

import java.awt.BorderLayout;
import java.awt.Button;
import java.awt.Frame;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class TestActionEvent2 {
	public static void main(String args[]) {
		//两个按钮，实现同一个监听
		 
		Frame frame = new Frame();
		Button button1 = new Button("start");

	}
}


class MyMonitor implements ActionListener{
	
	@Override
	public void actionPerformed(ActionEvent e) {
		//
		System.out.println("按钮被点击了"+e.getActionCommand());
	}
	
}

2.5、输入框TextField监听

package lesson2;

import java.awt.Frame;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.sound.midi.Soundbank;

public class TestText01 {
	public static void main(String args[]) {
		//启动！
		new MyFrame();
	}
}

class MyFrame extends Frame{
	public MyFrame() {
		TextField textField = new TextField();//写单行文本
		add(textField);
		
		//监听这个文本框输入的文字
		MyActionListen02 myActionListen02 = new MyActionListen02();		//监听这个文本框输入的文字
		//按下enter就会触发这个输入框的时间
		textField.addActionListener(myActionListen02);
		//设置替换编码
		textField.setEchoChar('*');
		
		setVisible(true);
		pack();
	}
}

class MyActionListen02 implements ActionListener{
	@Override
	public void actionPerformed(ActionEvent e) {

		TextField field = (TextField)e.getSource();//获得一些资源
		System.out.println(field.getText());//获得输入框中的文本
		field.setText("");//清空
	}
}

2.6、简易计算器，组合与内部类

package lesson2;

import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class TestCalc {
	public static void main(String args[]) {
		new Calculator().loadFrame();
	}
}

//计算机类
class Calculator extends Frame{
	//属性
	TextField num1,num2,num3;
	//方法
	public void loadFrame() {
		//三个文本框
		num1 = new TextField(10);
		num2 = new TextField(10);
		num3 = new TextField(20);
		Button button = new Button("=");
		Label label = new Label("+");
		
		button.addActionListener(new MyCalculatorListener(this));
		//布局	
		setLayout(new FlowLayout());
		add(num1);
		add(label);
		add(num2);
		add(button);
		add(num3);
		
		pack();
		setVisible(true);
	}
	
}

class MyCalculatorListener implements ActionListener{
	//获取计算机这个对象
	Calculator calculator = null;
	public MyCalculatorListener(Calculator calculator) {
		this.calculator = calculator;
	} 
	
	@Override
	public void actionPerformed(ActionEvent e) {
		//获得加数和被加数
		//将这个值加法运算后，放到第三个框
		//清除前两个框
		int n1 = Integer.parseInt(calculator.num1.getText());
		int n2 = Integer.parseInt(calculator.num2.getText());
		
		calculator.num3.setText(""+(n1+n2));
		calculator.num1.setText("");
		calculator.num2.setText("");

	}
}

//监听器类
/*
 * 
class MyCalculatorListener implements ActionListener{
	//获取三个变量
	private TextField num1,num2,num3;
	public MyCalculatorListener(TextField num1,TextField num2,TextField num3) {
		this.num1 = num1; 
		this.num2 = num2; 
		this.num3 = num3; 
	} 
	
	@Override
	public void actionPerformed(ActionEvent e) {
		//获得加数和被加数
		int n1 = Integer.parseInt(num1.getText());
		int n2 = Integer.parseInt(num2.getText());
		
		//将这个值加法运算后，放到第三个框
		num3.setText(""+(n1+n2));
		
		//清除前两个框
		num1.setText("");
		num2.setText("");
	}
}
*/

2.7、画笔

package lesson3;

import java.awt.*;
import java.awt.Paint;
import java.awt.PaintContext;

public class TestPaint {
	public static void main(String args[]) {
		new MyPaint().loadFrame();
	}
}
class MyPaint extends Frame{
	public void loadFrame() {
		setBounds(200, 200, 600, 500);
		setVisible(true);
	}
	
	//画笔
	public void paint(Graphics g) {
		//画笔，需要有颜色，画笔可以画画
		g.setColor(Color.red);
		g.drawOval(100, 100, 100, 100);
		g.fillOval(300, 300, 100, 100);
		
		g.setColor(Color.GREEN);
		g.fillRect(150, 200, 200, 200);
	}
}

2.8、鼠标监听

目的：想要实现鼠标画画！

import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.ArrayList;
import java.util.Iterator;

public class TestMouseListen {
	public static void main(String args[]) {
		new MyFrame("画图");
	}
}

class MyFrame extends Frame{
	//画画需要画笔，需要监听鼠标当前的位置，需要集合存储这个点
	ArrayList points;
	
	public MyFrame(String title) {
		super(title);
		setBounds(200, 200, 400, 300);
		//存储鼠标的点
		points = new ArrayList<>();
		setVisible(true);
		
		//鼠标监听器，正对这个窗口
		this.addMouseListener(new MyMouseListener());
	}
	
	public void paint( g) {
		//画画，监听鼠标的事件 
		Iterator iterator = points.iterator();
		while (iterator.hasNext()) {
			Point point = (Point) iterator.next();
			g.setColor(Color.CYAN);
			g.fillOval(point.x, point.y, 10, 10);
		}
	}
	
	//添加点到界面上
	public void addPoint(Point point) {
		points.add(point);
	}
	
	//适配器模式
	private class MyMouseListener extends MouseAdapter{
		//按下，弹起，按住不放
		public void mouseClicked(MouseEvent e) {
			MyFrame myFrame = (MyFrame) e.getSource();
			//我们点击的时候，就会在界面上产生一个点
			//这个点就是鼠标的点
			myFrame.addPoint(new Point(e.getX(),e.getY()));
			
			//每次点击鼠标都需要重画一遍
			myFrame.repaint();//每次刷新	
		}
	}
}

2.9、窗口监听

import java.awt.Color;
import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestWindow {
	public static void main(String aegs[]) {
		new WindowFrame();
	}
}
class WindowFrame extends Frame{
	public WindowFrame() {
		setBackground(Color.DARK_GRAY);
		setBounds(100, 100, 200, 200);		
		setVisible(true);
		addWindowListener(new MyWindowListen());
	}
	
	class MyWindowListen extends WindowAdapter{
		@Override
		public void windowClosing(WindowEvent e) {
			setVisible(false);//隐藏窗口，通过按钮
			System.exit(0);//正常退出
		}
	}
}

优化后：

package lesson3;

import java.awt.Color;
import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestWindow {
	public static void main(String aegs[]) {
		new WindowFrame();
	}
}
class WindowFrame extends Frame{
	public WindowFrame() {
		setBackground(Color.DARK_GRAY);
		setBounds(100, 100, 200, 200);		
		setVisible(true);
		
		this.addWindowListener(new WindowAdapter() {
			@Override
			public void windowClosing(WindowEvent e) {
				System.out.println("windowClosing!");
				setVisible(false);//隐藏窗口，通过按钮
				System.exit(0);//正常退出
			}
			
			@Override
			public void windowActivated(WindowEvent e) {
				WindowFrame source = (WindowFrame) e.getSource();
				source.setTitle("你好棒!");
				System.out.println("windowActivated!");
			}
		});
	}
}

2.10、键盘监听

package lesson3;

import java.awt.Frame;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;

public class TestKeyListener {
	public static void main(String args[]) {
		new KeyFrame();
	}
}

class KeyFrame extends Frame{
	public KeyFrame() {
		setBounds(1, 2, 300, 400);
		setVisible(true);
		
		this.addKeyListener(new KeyAdapter() {
			//键盘按下
			@Override
			public void keyPressed(KeyEvent e) {
				//获取键盘下的键是什么
				int keyCode = e.getKeyCode();
				if(keyCode == KeyEvent.VK_UP) {
					System.out.println("你按下了上键！");
				}
				//根据按下不同的操作，产生不同的结果

			}
		});
	}
}

		//设置文字Jlabel
		JLabel label = new JLabel("不欢迎请滚!");
		jFrame.add(label);
		
		//让我们的文本标签居中
		label.setHorizontalAlignment(SwingConstants.CENTER);
		
		//实例化对象
		Container container = jFrame.getContentPane();
		container.setBackground(Color.YELLOW);
		
		//关闭事件
		jFrame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
	}

		Container  container =  this.getContentPane();
		//绝对布局
		container.setLayout(null);
		
		//按钮
		JButton button = new JButton("点击弹出一个弹窗");
		button.setBounds(30,30,200,200);
		
		//点击这个按钮的时候，弹出一个弹窗
		button.addActionListener(new ActionListener() {
			@Override
